Enclave FWD V6-3.6L (2008)
Important: A special anti-seize compound is used in the HO2S threads. The compound consists of liquid graphite and glass beads. The graphite
tends to burn away, but the glass beads remain, making the sensor easier to remove. New, or service replacement sensors already have the
compound applied to the threads. If the sensor is removed from an exhaust component and if for any reason the sensor is to reinstalled, the
threads must have anti-seize compound applied before the reinstallation.
1. If reinstalling the old sensor, coat the threads with anti-seize compound GM P/N 12377953, or equivalent.
Notice: Refer to Fastener Notice.
2. Install the HO2S (2) to the exhaust manifold.
Tighten the sensor to 42 N.m (31 lb ft).
3. Connect the engine wiring harness electrical connector (3) to the HO2S electrical connector (2).
4. Install the HO2S electrical connector retainer to the engine wiring harness clip (1).
5. Lower the vehicle.
